Technical progress is such a double edged sword. We can't imagine slow handlooms today but in the 1700's it was incomprehensible there would be anything else. Our spinning technology still can not create some of the yarns handspinners created historically. the sheers of Egypt have not been equaled, yet.Elon Musk just came out and said he's fairly confident Govts are going to start outlawing personal vehicle ownership by 2025. I believe him, he's been working side by side with govt agencies towards elec cars( his company had a large loan from the gov for his start up). Like all technology, i can see the good in it, but know it wont be used that way. It'll be a cold day in hell I give up the freedom of owning and driving my vehicle.
Ray Kurzweil and Google etc... I am so ambivalent.
